I get an extremely intermittent cell signal at my apartment so am always on UMA. Google places me in 3 different locations randomly, Malibu - about 15 miles away, Playa Del Rey about 5 miles away, about 1/4 mile away down by the beach.

The building is physically surrounded by higher land that blocks the 2 nearby towers. So my guess is stray cell signals are getting bounced across the water. I always assumed the 1 or 2 bars I sometimes get is from the nearby towers. But perhaps it's from a tower several miles away.

I just noticed that if I go into the kitchen which has the best cell signal, it'll show me at the tower a couple blocks away.

In my case, it claims accuracy to within 1700 meters, but I'm actually outside of the "blue zone" by at least another 800 meters. My home is on higher ground than much of the surrounding area, so my signal strength may be a bit higher than expected given an assumption of flat terrain (and the corresponding assumption that the accuracy indication is based on signal strength).

Assuming that the radius of the circle is the 1700 meters, I am another diameter away, making for 5100 meters away from the tower. I am far outside the light blue circle.

I live in the west side of Houston and the accuracy is pretty bad. The funny part is when I drove east towards one of the towers which should have increased the accuracy the next calculation showed me about 5 miles further west.

This is being advertised as a beta but the "GPS" function appears closer to an alpha. I plan on checking the percision of the calculations and see if the software give the same wrong position time after time.

I will also be in Tucson next week and it will be interesting to see how it works there.

I believe the radius of the circle is whatever the "Accuracy to . . ." banner states. Others have posted different accuracy values, so I don't think it can be assumed it's always 1700 meters (not saying that you've made that assumption, either ).

That's exactly what I think too - when it says 5000 meters, the radius is 5000 meters. Sitting at my desk, I am back on my ocean tower again, with a 1700 meter radius, and I am probably 4-5 diameters away from the outer edge of the circle.

For me it just seems like a tower locator. It does accurately tell me what tower I'm on. It doesn't follow me along. It will occasionally bump a few miles to another location which, from the site below, appears to be another tower. For real location you need a GPS. For using a "current location for a search it works great.
